1.8" TFT Display Driver

Post by grimmjaw »

Hi,

I have a problem with the colour definition:
Form the header file:

#define ST7735_BLUE 0x001F
#define ST7735_RED 0xF800

But I got blue instead of red.
from the your website the driver chip for 1.8" TFT Display is ST77350 but with closer inspection
I noticed that the chip is actually HC4050M from TI.
Can anyone shed a light on this. Is the TFT use different driver chips? If yes where could I find the header file
for HC4050M

Thank you.

Our suppliers periodically change their specs. It's something we have no control over. Whenever a change occurs, we update our library as necessary.
